Humphrey Smith Motorsports’ Mike Bliss would miss the race Sunday if qualifying for the Kobalt Tools 400 is rained out today. The National Weather Service predicts an 80 percent chance of rain until 6 p.m. Eastern and then a 35 percent chance for the rest of the day. As of 10:45 a.m. Eastern, the track was wet from rain.

If qualifying, scheduled for 6:40 p.m. Eastern, is rained out, the 43-car field would be set by 2012 owner points. There are 44 entries.

The top 36 drivers in 2012 owner points would make the race. Trevor Bayne was 36th in 2012 points even though his Wood Brothers team competed in just 16 races last year.

Then, according to the NASCAR rulebook, any winning driver or team owner from 2012 or 2013, as well as any past champions, make the field. But all of those were in the top 36 in points.

Then, because it’s one of the first three races of this season, any of the top 36 drivers in owner points for this year would make the field. That means that Danica Patrick (23rd), David Stremme (27th) and Michael McDowell (28th) all would make it.

Then it goes to qualifying attempts this year, with ties broken by owner points. That gets in four drivers whose teams have attempted both races: Scott Speed (37th in owner points), Landon Cassill (38th), Joe Nemechek (41st) and Josh Wise (42nd).

That leaves Bliss, 44th in owner points, out of the field.

If drivers get any practice today, the starting order (not who gets in, just how they line up for the start of the race) would be determined by practice speed.

If they do not practice, the lineup would be determined by the top 36 in 2012 owner points, meaning champion Brad Keselowski would be on the pole, with Patrick, Stremme, McDowell, Speed, Cassill, Nemechek and Wise rounding out the field.

The on-track schedule today has Nationwide Series practice at noon Eastern, followed by Cup practice at 3 p.m., Nationwide practice at 4:40 and then Cup qualifying at 6:40 p.m.
